Jackson said he received upbeat advice from Manziel, who urged his 19-year-old pal to fully embrace his college experience. Jackson has at least one more season to play in the NCAA ranks before he can declare for the 2018 NFL Draft.

“Johnny Manziel, he was telling me a lot of positive things,” Jackson explained Monday on “The Dan Patrick Show,”via Larry Brown Sports. “He came by my room, too. He was just telling me, ‘Man, have fun in college. You only can stay here a certain amount of time. Just have fun with it.'”

It’s not hard to imagine Manziel delivering the pep talk with a nostalgic gleam in his eye. The one-time Texas A&M superstar won the Heisman in 2012, and was drafted 22nd overall by the Cleveland Browns two years later.

His career rapidly devolved from there as his just-have-fun persona was shattered by a sequence of troubling off-field incidents — he was indicted earlier this year on a misdemeanor domestic violence charge — and concerns about his health as he battled substance abuse. Manziel was released in March, and remains a free agent.
